IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent N0. 22,629, dated January 18, 1859.

To all whom it may concern:

Be it known that I, G. D. OOLTON, of Galesburg, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Flows; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the employment of the pole, which reaches forward and rests its forward end on the neck-yoke, in combination with other parts of the plow, as will be hereinafter described.

In the annexed drawings, Figure 1 is a perspective view of the plow. Fig. 2 is a side elevation.

In the figures, A A represent the two wheels which support the plow and frame. One of these wheels is made larger than the other, as will be seen.

Bis the axle to which the wheels are secured.

H represents a bar, one end of which is attached to the axle at one side, near one of the wheels, by means of a bolt. The other end of said bar, being parallel with axle, is mortised with the beam D. The beam D at its back end, near the point where the bar is attached, is provided with a hole into which passes a pin on the axle. The back end of the beam plays up and down upon this pin, and it may be operated and regulated by means of a lever or cord, or in any other convenient manner.

Gis a pole, which is secured by a hinge or loose bolt (so that it may have play) to the back end of the beam and on top of it. This pole U reaches forward, and when the horses or cattle are attached to the plow, it passes between them and the pin 1 catches upon the neck-yoke, and the pole rests upon said neckyoke.

d is a standard secured to the beam, and e is a standard secured to the pole O.

E is a lever, which is secured to both ofthe standards d and e.

a is an upright attached to the back end of the pole, and it is provided with slots or grooves into which pass the lever E, and by means of which it is stationed at any desired point.

F represents the plow, which is secured to the beam, back of its center.

It will readily be seen, now, that by pressing upon the lever E, so long as the pole G rests stationary upon neck-yoke, the beam D will be elevated, and that by raising the back end the beam will be depressed, thus raising or low- D, the standards d and c, upright a, lever E,

brace 2, bar H, axle B, and pole 0, said pole reaching forward and resting upon the neckyoke, in the manner and for the purpose herein specified.
